Refraction has no effect on azimuth - so none.

I need some assistance. I understand the formula to calculate the
change in altitude of the sun due to refraction.

What I can’t figure out is once altitude is changed what does that do
to all the other co-ordinates of the sun’s position.
What I am looking for is a way to calculate the temporal hour
including refraction, which is what you would see on an actual ancient
sundial.
My problem is that the results that I get for the temporal hour
including refraction can be up to a fifteen minute difference at the
11th temporal hour, which doesn’t seem right.
I am obviously not doing something right.
Any help would be appreciated.
